The Sun Hydraulics DNCADCN728 (DNCADCN728) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, significantly reducing oil loss during shifting which is particularly advantageous in pilot control circuits. The DNCADCN728 operates effectively with port 3 as the inlet and port 1 as the tank outlet; however, while reverse flow is possible, optimal performance in this configuration cannot be assured. Engineered for durability and reliability, the solenoid tube assembly of the DNCADCN728 is fatigue rated for service up to 5000 psi (350 bar). The valve does not require a minimum hydraulic pressure to function due to its direct actuation design. It incorporates EPDM seals specifically for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Additionally, the valve\u2019s wet armature design means that the working fluid surrounds the armature which may affect fluid integrity if subjected to prolonged heat exposure from an energized coil. The DNCADCN728 offers a variety of coil termination and voltage options, including models with surge protection. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Connector options for coils are rated up to IP69K for robust environmental protection. The construction of this model minimizes internal parts binding due to installation torque or machining variations through its floating style design. Key specifications include an 8 gpm (30 L/min) capacity, maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and a maximum switching frequency of 15,000 cycles per hour. These features make the DNCADCN728 an efficient solution for various high-demand applications requiring precise fluid control and rapid response times.
